Barydia Guenée, 1852 . Type species: Barydia bufo Guenée, 1852 . Hist. Nat. Insectes. 6: 410, pl 18, fig. 1.

Adults. ( Figure 1E View FIGURE 1 ) Head: antennae of male simple filiform; antennal tufts present; head tightly covered in scales; third segment of labial palpus very long. Thorax: male prothoracic leg without scent pocket on femur; tarsal claws bifid. Wings: males 30 to 50 mm, the forewing pattern molted brown forewing with a light brown semicircle apically; accessory cell present; hindwing simple dark brown with Sc-Rs stalked. Abdomen: brown. The seventh abdominal segment has a unique modification consisting of a pair of sclerotized, extremely sharp, inwardly curved forked projections that extend beyond the length of the eighth segment and entirety of genitalia capsule ( Figure 4L View FIGURE 4 ). Male terminalia ( Figure 4M View FIGURE 4 , 5G View FIGURE 5 ): The eighth tergite has two long and thin processes at the central base; the eighth sternite is well-sclerotized, with a W-shaped base, and a V-shaped apex; valvae small, SSO slightly developed; costulae present; uncus bulbous with tiny mesal bifid process; socii small upcurved; juxta squared. Aedeagus long and curved with a spined process apically.

Diagnosis. Barydia bufo cannot be mistaken for any other genus. The habitus of the single large species of the genus is quite unique considering the apical mark, simple antennae, and highly tufted labial palpi. In addition, the abdominal characters are wholly unique among the subfamily (and among all Notodontidae to our knowledge), due to the presence of a highly modified seventh sternite with sharp, fang-like projections ( Fig. 4L View FIGURE 4 ) in addition to the typically modified eighth tergite ( Fig. 4M View FIGURE 4 ).

Comments. The genus was established in the Noctuidae , placed in Notodontidae by Watson et al. (1980) and first assigned to Nystaleinae by Becker (2014).

Distribution. French Guiana.
